Cecidomyiidae, galls on Lead plant - Rhopalomyia undescribed-species-on-amorpha

Cecidomyiidae, galls on Lead plant - Rhopalomyia undescribed-species-on-amorpha

Is there a category for unidentified galls? (I assume there is, I just can't find it.)
These galls on Lead plant, Amorpha canescens, are the same shape as but they are not on the leaflets but rather on the woody branch/rib. They also turn red earlier in the year than the leaflet galls and sometimes there is a long linear row of them.

Same thing, I think. These galls can be on the leaflet, rachis, or flower stalk.
Unidentified galls here.

 
Thanks.
This was the first time I'd ever seen them on the rachis and clustered several in a row.
